Leum Patent No. 87,948, me Mme 16, 1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'itvmag/ concern,.-

Be it known that I, It. O.'LoWREY, of Salem, inthe county of IVashington, and State of New York, have invented certain new'and useful Improvements in Spring-Bed Bottoms and I do hereby declare that'the following is a full, clear, Aand exact description thereof, reference being had to the accompanying, drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur;

-To enable others skilled inthe art to constl'uct and use my invention, I will proceed to describe it..v

My invention relates to spring-bed bottoms, and consists in-new and certain improvements in the bed-bottom forwhich Letters Patent, No. 74,388, were granted me, February 11, 1868.

By means of these improvements I am able to produce a vbetter construction and arrangement of the springs and slats, and to make a more elastic, durable, and cheap spring-bed bottom.

In ithe drawings- Figure l 'is a sectional view cfa part detached, showing the forms of the springs, and the mode of connecting them with the cross-pieces and slats;

Figure 2 is a perspective'view; y

Fignre is a View of a part detached; Figure 4 is an end view of a part detached, and partly in section; and

'gnre 5 is a view of a modification of the vspring'.

I construct my bed-bottom of a serie`s'ofV longitudinal slats, A, which I connect with two .dat cross-pieces, B and, by wire springs D, arranged as clearly shown in iig; A2.

. Each of the slats A, I one at each end.

These springs D provide with tworsp'rings, D,-

I make of any kind of wire having suitable elasticity and strength, and form them as clearly shown in gs. 1 and 4, or in the modified form shown in iig. 5.

Each o f these springs I make of a single piece of wire, bending the central portion as shown in iig. 4, so as to form a hook, a, and the legs or sides, so as to form coils l, and the ends, so that they may be 'conveniently attached to the cross-pieces B and O, as shown in figs. 1, 2, and 4.

N eareach end of these slats A, I out a hole, c, which may be Vsquare or oblong, and of proper size to permit the hook q. of the spring tobe inserted therein, as represented in fig-1.

The edge of thc-bar, on that side ofthe hole nearest the end of the slats, is cut away, or bev'elled from each side toward the centre of the slat, as shown more clearly inl fig. 5, th'ns forming a recess, in which the point of the hook a restsfso as notto be thrown above thesnrface of the slat, and which also permits the slat, when bent, or sagged by use, to be turned over, and usedA with equal facility, the other side up.

This shaped opening makes a better bearing for the hooks-.(0,l allows an easier and freer motion of the slats and springs, and, by letting the hooks crest a little below the surface of the slats, they do not rub against and wear holes in the ticking of the bed.

'0, and connect them with the slats A, that when in their natural position, their hooks wwill .be a little in the rear of thevvertical plane passing through their points of connection with the cross -.bars, and when pressed down, will be a little in front of it.

The coils b of the springs D, are so made as to be all in a line when the springs are attached to the crossbars.

Between these. coils o, I insert blocks E, with their ends entering in the coils. These blocks E are formed and'shaped as shown in iig. 3, and arranged as shown in iigs. 2 and 4. They ser-ve to connect and-hold the springs D in position, without interfering with their moving independently of each other..

The legs or sides of thesprings D are set far enough apart to permit the ends of the slats A, to which they are connected,` to pass betweenv themv when pressed down, as shown in red lines in' iig. l.

It is obvious that vthese hooks D may be modified in form, and connected with the cross-bars and slats, as shown in iig. 5, but I prefer to make and arrange them as in figs. l, 2, and "i In this way I am able to make a complete bed-bottom, as shown in hg. 2, which can be readily and conveniently inserted within the frame of a bedstead.

It is simple, compact, and durable; each slat moves independent of the other, and in the event Aof either of the slats becoming bent or sprung, itcan'be easily turned over, or if broken, can be conveniently removed, and another put in its place.

In my former patent, mentioned above, lthe springs at the head are stiii'er than those at the foot. This peculiarity I preserve in my present construction.

My present improvement consists, principally, in arranging the springs onA two cross-pieces, and in such `a way that there will he no necessity of attaching the' cross-pieces together by longitudinal pieces, and in providing the slats with wedge-shapedopenings, and the springs with connecting and supporting-blocks.

Having thus described my invention,

2. Connecting the adjoining springs of the series by means of' the blocks E, constructedand applied as shownand described.
